End-to-End O-RAN Security Architecture, Threat Surface, Coverage, and the Case of the Open Fronthaul. (arXiv:2304.05513v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
O-RAN establishes an advanced radio access network (RAN) architecture that
supports inter-operable, multi-vendor, and artificial intelligence (AI)
controlled wireless access networks. The unique components, interfaces, and
technologies of O-RAN differentiate it from the 3GPP RAN. Because O-RAN
supports 3GPP protocols, currently 4G and 5G, while offering additional network
interfaces and controllers, it has a larger attack surface. The O-RAN security
requirements, vulnerabilities, threats, and countermeasures must be carefully
assessed for it to become a platform for 5G Advanced and future …
